摘　　要：2007年8-10月、2008年3-7月在内蒙古达赉湖自然保护区共收集到130份貉（Nyctereutes procyonoides）的粪便,采用粪便分析法中的频率法和剩余物相对干重法对其进行分析。貉的食物主要是鸟类（出现率39.81%,剩余物相对干重百分比52.60%）和啮齿类（出现率22.69%,剩余物相对干重百分比25.85%）,其次为昆虫（出现率26.39%,剩余物相对干重百分比13.32%）、植物（出现率7.41%,剩余物相对干重百分比1.39%）、鱼类（出现率2.31%,剩余物相对干重百分比5.79%）及虾类（出现率0.93%,剩余物相对干重百分比0.85%）,软体动物（出项率0.46%,剩余物相对干重百分比0.20%）极少,未见到大型有蹄类动物出现。本文还对两种粪便分析法所得的结果进行了比较,发现这两种方法对貉食物种类的分析评述上无显著差异。Diet composition of Raccoon Dog （Nyctereutes procyonoides） was checked by analyzing 130 Raccoon Dog dung collected from August 2007 to July 2008 in the Dalaihu Nature Reserve, inter Mongolia China. Both percentage occurrence and percentage of relative weight of remains were measured for analysis. Birds （39.81% occurrence vs. 52.60% relative weight） and rodents （22.69% occurrence vs. 25.85% relative weight） were the major food items of Raccoon Dog. Other food item components were insects （26.39% occurrence vs. 13.32% relative weight）, plants （7.41% occurrence vs. 1.39% relative weight）, fishes （2.31% occurrence vs. 5.79% relative weight）, shrimps （0.93% occurrence vs. 0.85% relative weight）, and mollusk （0.46% occurrence vs. 0.20% relative weight）. Ungulates were not found in the dung. The results from both measurements were not difference, both of them can be used on analysis of food items of Raccoon Dog.
